  I have try to lauch a daemonSet with:
  kubectl apply -f fluentd.yaml

=> fluentd.yaml is:

apiVersion: extensions/v1beta1
kind: DaemonSet
metadata:
  name: fluentd
  namespace: kube-system
  labels:
    app: fluentd
spec:
  template:
    metadata:
      labels:
        app: fluentd
    spec:
      containers:
      - name: fluentd
        image: fluent/fluentd:v0.14.10
        resources:
          limits:
            memory: 200Mi
          requests:
            cpu: 100m
            memory: 200Mi
        volumeMounts:
        - name: varlog
          mountPath: /var/log
        - name: varlibdockercontainers
          mountPath: /var/lib/docker/containers
          readOnly: true
      terminationGracePeriodSeconds: 30
      volumes:
      - name: varlog
        hostPath:
          path: /var/log
      - name: varlibdockercontainers
        hostPath:
          path: /var/lib/docker/containers

and:
kubectl describe daemonset fluentd
Error from server (NotFound): daemonsets.extensions "fluentd" not found

Any idea what is happening?

/sig apps

@MrMic After version 1.9 I think extensions group should be migrated to apps as references in the documentation indicate: https://kubernetes.io/docs/reference/workloads-18-19/

Are you sure you are in the right namespace?

What does this return:
kubectl describe daemonset fluentd -n kube-system

[MrMic]

Yes @liggitt , it works !
Thank you.
But why is there no pod ?

[liggitt]

check for pods in the same namespace (kubectl get pods -n kube-system), and check the controller manager logs if you are not seeing the expected pods
